A method of gamma correction for a liquid crystal display (LCD) having an LCD panel. In one embodiment, the method includes the steps of dividing the LCD panel into N areas along a gate scanning direction, each area having a corresponding gamma and being characterized with a corresponding voltage-transmittance function, and determining grey level voltages of each area for each of a set of grey levels from the corresponding voltage-transmittance function of the area and a desired gamma curve of the LCD panel such that when the grey level voltages are respectively applied to the N areas for a grey level, a light transmittance through each area is substantially uniform and equals to a corresponding brightness.
